SPECIFICATION forming part of Letters Patent No. 310,553, dated January 13, 1885.

Application filed April 22, 1884. (No model.) A

To aZZ whom it may concern:

Be it known that I, DAVID C. BARTON, of Rocheport, in the county of Boone and State ofMissouri,have invented a new and Improved Oar-Coupling, of which the following is a full,

clear, and exact description.

The invention consists in the construction and arrangement of parts, as will be hereinafter fully described and claimed.

[0 Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is aside view and longitudinal sectional elevation of my improved car-coupler, showing the couplings secured on cars. Fig.2 is an end view of the car and draw head. Fig. 3 is aside view of thelink. Fig. 4 is a plan view of the same. Fig. 51is a side view of the swivel-link. Figs-6 and 7 are end views of the two sections of the swivellink.

The draw-head A, which is of the usual construction, is provided in the top with a longitudinal slot, G. The coupling-pin D is of such length that it can project some distance from the top of the draw-head, and the upper end of the pinis guided by an aperturedarm, E, on the top of the draw-head.

0 The couplingpin is provided with a cross-pin projection or flange, D, a-short distance from the lower end, to limit the downward movement of the pin. A plate, F, is held to slide on the draw-head in the direction of the length 5 of the same, and is provided with a pin, G, which projects through the slot 0 down into the drawhead. The slide F slides under a casing, H, held on the top of the draw-head, and the said slide F is connected with the top 40 of the coupling-pin D by a chain or wire, J, passing through an opening, a, in the casing- H. A chain, K, extends from the top of the coupling pin D through suitable guide staples to the roof of the car, and the chain is pro- 4 5 vided at its upper end with a suitable ring or handle. Two levers, L, pivoted on the ends of the cars, have forks M formed on their inner ends, the prongs of the forks extending into an annular groove, N, in the coupling pin directly above the cross-piece or flange D. Chains Q are held on the end of the car, forthe purpose of holding the outer ends of the levers L lowered, and thus preventing the pin from coupling. The couplingdink O is made straight, or has one end bent upward and 5 the other end bent downward, as shown in Fi 3. On the center part of the link a heavy rubber bumper, P, is securely held, which passes in between the ends of the draw-heads when the cars are coupled. If desired, a (DC swivel-link can be used, as shown in Fig. 5. One section, Q, is provided in the inner end of its crosspiece with a slot, m, parallel with the plane of the section, and the other section, B, is provided with a stem having a crosspiece, a, at right angles to the plane of the section B. \Vhen the cars are coupled by means of the swivel-link, the two link-sections are in the horizontal plane, and the crosspiece a, which extends across the inner sur- 7O face of the inner cross-piece of the section Q, is at right angles to the plane of the two sections. If the cars run off the track and one car turns over, the link-sections Q and R are brought in planes at right angles to each other. The cross-piecen is parallel with the slot in and can slide through the same, and thus the cars are uncoupled automatically, and the car that has been overturned cannot cause derailment of the other cars. If the link is held by the s coupling-pin D, as shown in Fig. 1, on the right-hand side, the couplingpin D can be moved upward, either by means of the chain K or by means of one of thelevers L. Thereby the chain J is drawn taut, and as it is con- 8 nected with the inner end of the slide F and passes through the aperture a in the casing H, the slide F is moved toward the outer end of the draw-head and under the coupling-pin D, thus preventing the same from dropping. 0 When the link enters the draw-head it strikes the pin G and pushes the same, with the slide F," inward, thus moving the slide F from un der the coupling-pin, which drops, thus holding the link and coupling the cars. ,95 Having thus described inyinvention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination, in a car-coupling, of the draw-hcad .A and coupling-pin D, formed I00 with a groove N, with the levers pivoted to piece \vithastein havingaeross pieee, n, on its the car on either side of the coupling-pin, and end. substantially as herein shown and deforked at their adj aeent ends, substantially as scribed.
